Wheel weight is a designed piece of metal that ensure proper tire balance preventing bad wear of the tire material. In the 1930´s because of its density, low cost, and malleability, lead was used in wheel weights worldwide.
Research indicates people are exposed to lead fragments and
dust when lead wheel weights fall from motor vehicles onto roadways and are
then crushed and worn down by traffic. Lead can contribute to soil, surface,
and groundwater contamination and pose hazards to downstream aquatic life.
As some efforts are being made on the pursue of more
Biological aid and enviromental friendly practices worlwide, some plans
preventing and banning the use of lead as a building material are taking over
many States and movements of support can be seen online.
Most new cars now come with coated steel or zinc wheel
weights, which have passed the same safety and use tests as lead weights.
However, most tires get lead wheel weights when they are repaired or replaced.
An environmentally preferred wheel weight is a wheel weight
that does not include more than 0.5 percent by weight of lead or any other
chemical on Ecology’s PBT list. This means that wheel weights must not contain
substances like cadmium or mercury either.
As we care for Best Practices, our products are designed to
be environmental friendly, you can check our alloys Wheel weights here.
Ask your supplier for assurance that the weights you buy are
